Gwen Stefani thinks Blake Shelton got "sexier" after losing his Sexiest Man Alive title

She said: "Yeah, that was hard. It was hard on me because it made me feel..."

Talk show host Ellen DeGeneres interrupted: "Where's the sexy?"

Gwen agreed and said: "Exactly... [No], honestly, he got sexier."

The blonde beauty then got flustered and let slip an accidental innuendo when Ellen continued to quiz her about the more intimate parts of her relationship.

The 60-year-old presenter asked: "When the title came upon him, did you notice that he became better in bed?"

Ellen replied: "What? It's a yes or no answer."

Gwen then asked for the "next question", prompting Ellen to try and get the 'Hollaback Girl' singer to admit she and 'The Voice' coach were engaged by claiming he had already confided in her about it.

Her guest replied: "No he didn't! No we're not! What are you talking about? We're not! We're not engaged and we're not married. And he's my boyfriend. Still."

Ellen then suggested Gwen - who has sons Kingston, 12, Zuma, 10, and four-year-old Apollo with ex-husband Gavin Rossdale - should pop the question instead.

She replied: "Every time I come here I think it's going to be so 'I got this,' you know?"

Meanwhile, Blake recently admitted he felt "sexy ended" when he gave up his title.

He said: "Can I be honest? I feel like when I gave up my crown, sexy ended.

"It just ended in the world. So until I get it back, it doesn't exist anymore.

"I'm sure this new guy is a nice guy. He's a great guy. I mean, I don't see it myself. I'm really the only person I've ever seen it with, but..."
